Springfield Ginger Marmalade
Ingredients 
2-3 grapefruit 
1-2 oranges 
1-2 lemons 
2.75 litres water 
1 x 8cm length (50g) fresh ginger, cut into 4 strips and tied 
 together in a piece of muslin 
2kg sugar 
4 pieces (65g) preserved stem ginger in syrup, finely diced 
-
Method 
Wash the fruit and slice the ends off. Using a very sharp knife 
 (or mandoline if you have one), slice the fruit very thinly. 
 Weigh the fruit and retain 600g grapefruit, 250g orange and 
 150g lemon.This gives 1kg of fruit, the quantity required for 
 the 2kg sugar in this recipe. Place the fruit and any pips in a 
 large non-reactive bowl, cover with water & refrigerate overnight. 
 (If left any longer, the fruit will not achieve such a good jell or set.)
The following day, transfer the fruit and water to a non-reactive 
 preserving pan (or a wide, non-reactive saucepan with sloping sides), 
 add the fresh ginger and bring to the boil. 
 Turn down the heat and simmer for 30-45 minutes until the fruit is 
 tender (peel rubbed between your finger and thumb should almost disappear). Take care not to overcook, which at this stage would 
 decrease the flavour and destroy the colour of the fruit. 
 It is important to take this stage gently and slowly as the addition 
 of sugar stops the fruit tenderising further.
Decrease the heat to low and add the sugar and stem ginger, 
 stirring with a metal spoon until the sugar is dissolved, then 
 increase the heat and bring to the boil. Boil for 20-25 mins 
 until the mixture starts to jell (or set).
Check this by doing a plate test: 
 take the marmalade off the heat and spoon a little on to a cold 
 saucer and place in the freezer for 2-3 minutes. Remove it from 
 the freezer and part the marmalade on the saucer with your finger. 
 If it is at setting point it will stay apart and have a skin on it. 
 If not, place the saucepan back on the stove, boil for another 
 few minutes then try the plate test again.
Once setting point is reached, take the marmalade off the heat and 
 leave in the saucepan to cool a little (about 15 minutes). 
 This helps distribute the peel and ginger evenly.
 Discard fresh ginger muslin bag. Stir marmalade well, pour into hot 
 sterilised jars and seal. Store in a cool pantry for up to 1 year. 
 Makes 8-9 270ml jars.
